How does laser cutting machine technology deal with burrs puzzle everyone, how do burrs occur? What are the causes of burrs in sheet metal processing by laser cutting machines? Let's give you a brief analysis below.
How does the laser cutting machine technology deal with burrs? When some customers use laser cutting machines to process sheet metal, the results of the cut workpieces are very unsatisfactory, and there are many burrs, and then many customers start to doubt the quality of laser cutting machine products The problem is actually not the case. During the cutting process of the metal laser cutting machine, due to improper operation and technical problems, the processed materials should not produce burrs. Burrs can only be produced in metal cutting, and there is no burr problem in non-metal cutting. How do glitches occur? In fact, burrs are excessive residue particles on the surface of metal materials. If a piece of material has burrs, it can be qualitatively defective. The more burrs, the lower the quality. What are the causes of burrs in sheet metal processing by laser cutting machines? Let's give you a brief analysis below.
The working principle and technical analysis of the laser cutting machine have obtained the reasons and solutions for the burrs.
1. The up and down position of the focus of the beam is deviated.
Solution: Adjust the position of the focus and adjust it according to the offset position it produces.
2. The output power of the machine is not enough.
Solution: Check whether the laser cutting machine is working properly. If it is abnormal, it needs to be repaired and maintained in time. If it is normal, check whether the output value is correct.
3. The wire cutting speed of the cutting machine is too slow.
Solution: Adjust and increase the wire cutting speed in time.
Fourth, the purity of the auxiliary gas of the cutting machine is not enough.
Solution: Explain how to improve the purity of the auxiliary gas.
5. The laser beam of the cutting machine has an offset.
Solution: Debug the focus and make adjustments in time
6. The instability of the laser cutting machine operating for too long.
Solution: Turn off the machine and restart it and let the machine rest.
The metal laser cutting machine is a precision machine, and the operation is also a delicate work. Often a data error will cause its work to run abnormally, so the work must be strict and precise to reduce and avoid errors.
The main reason for burrs in sheet metal processing by laser cutting machines; when the laser cutting machine is processing the workpiece, the high energy generated by the laser beam irradiating the surface of the workpiece quickly vaporizes and evaporates on the surface of the workpiece to achieve the purpose of cutting. But there is a core device that we must pay attention to, that is, auxiliary gas. The auxiliary gas is to blow off the slag on the surface of the workpiece when the irradiated surface of the workpiece is vaporized. If the auxiliary gas is not used, after the slag is cooled, burrs will be formed and attached to the cutting surface. This is the main reason for the formation of burrs.
Another reason is the quality of the equipment itself, as well as the parameter setting factor. When the customer purchases the laser cutting machine, a professional operator must debug the equipment.
Solutions to burrs in sheet metal processing by laser cutting machines;
1. Must be equipped with an air compressor and use auxiliary gas for cutting.
2. Find a professional operator to debug the parameters of the laser cutting machine until it is normal.
